LINER FOR CENTRIFUGAL CREAM-SEPA'RATORSJ Specification of Letters Patent.

Application filed. December 1%, 1906. Serial No. 347,788.

To rillwhoni it may concern:

..-Be it known that I, THOMAS W. MORGAN, a

citizen of'tlie United States of America, and a resident of Waterloo, Blackhawk county,

truncated cones, hollow and spaced apart,

and provided with means for permitting a current of the entering milk to ascend through channels therein, and having appropriate means for keeping such cones in the aimsment necessary in order to keep the said vertical channels unobstructed. This object I have accomplished bythe means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings,

in which Figure 1 is a central axial vertical section of a centrifugal cream separator bowl con 'taining my improved liner, and Fig. 2 is a "plan view of myimproved separating. cone,

showing the manner-in; which it is kept ina certain fixed position in the bowl.

Similar letters refer to similar parts throughout the several views.

I have shown a centrifugal cream separator of an ordinary type whose bowl is provided with a conical cover. The atter hasa cylindrical extension 'd provided with milk Said cover f is tact with the upper edgeof the bowl 9 by means of a clamping bolt 6 whose'flange a contacts with the upper edge of the cylindi'ical extension 65, the lower threaded end g of said bolt engaging-a threaded 0 ening in the bottom of the bowl. ,A conica separating device k is fitted within the conical cover 8 and has a flange k which contacts with the inner periphery of the cylindrical extension 1 between the milk exits c and the cream exit-s c. This separating device h is spaced I away sufiiciently from the inner periphery of the cover f to provide a space 'i in communi- 'cation with'the milk exits e, the inner periph'ery of the cone 7 cpnveying separated cream upward to the'creani exits The into the interior of thebowl g.

' THOMAS W. MORGAN, OF WATERLOO, IOWA, ASSIGNOR TO WILBYR W. MARSH, OF WATERL'OO,

My improved liner is composed era verti-.

cal series. of separated superposed truncated.

cones n, bein stud these separating cones as having a ourve of the same radius for a purpose tdbe. herein; after described. But said cones may, 'ifide spaced apar y-means of the sired, be otherwise formed without changing the principle of my invention.

s r. I iliave. shown in the drawings,

Tne lowermost cone n of said vertical see ries is fixedly connected to the lower corners of the vanes m of the cylinder'l; All of the cones n as well as the lowermost cone n have radial slots 0 in' communication with their central openings 8.

The device which I have adopted for holding said cones in a certain fixed alinement is the cylinder Z having a plurality of vertical wings orvanes m. The ollow cylinder Z is adapted to slip over and fit the exterior periphery of the clamping bolt 1) concentrically therewith and its outer periphery is spaced away from the inner edges of the cones n to afford concentric spaces 8 within which-is the cream zone of the bowl. The vanes 'm have a sufficient radial projection to, cause them to extend a short distance within the inner portion of the slots 0 contacting with the inner edges of said slots and holding all of said cones when placed .thereover so that the openingso-all register vertically and form continuous channels for the passage therethrough of ascending currents of separating milk. a

hen the separatin'g cones n are thus properly placed in-the bowl over the lowermost'cone n so that the vanes m cause all their apertures 0 to register and the cover f is clamped down on the bowl, the liner is in operative rotation, t e milk is introduced into said bowl'through the inlet band passes through the openings 39 radially outward toward the cone n and then moving upward through the apertures 0 in the cones n. Portions of the separating milk then move outward along the surfaces of said cones to the inner cry of the bowl along which the skimmed osition. Being set into rapid' periphmilk moves upward to the conduit i and milk exits e. The cream which is separated a in this process. moves inwardly to the cream zone and then upward to the cream exits c. When the cones are somewhat curved on the same radius as shown their interspaces gradually diminish in height from the inner edges of said cones outwardly and the eflect of the gradual approximation of the surfaces of said cones is to cause a progressive bafliing of the separating outwardly movin milk thereby alding in the separation of t e mi nut'er particles of cream in the milk in the outer zone of the bowl.

By the means shown the separating cones are not only provided with channels for the ascending currents of separating milk in what is called the neutral zone of the bowl but such cones are kept inthe same alinement and nevertheless are readily detachable whenit is desired to disassemble the liner.

, All the parts of the liner are thus easily assembled or disassembled for the purpose of cleaning oruse and being of simple are of inexpenslve construction.

Having described my invention; whatI claim as new, and desire to secure by Letters- Patent, is

A liner for a centrifugal cream separator, consisting in combination, of an axial inlet tube having discharge openings at its lower end, a removable cylinder seated concentrically about' said inlet tube above the latters discharge openings and provided with vertical radial vanes, a vertical series of hollow frusta, spaced apart, seated about said removable cylinder detachably and spaced apart therefrom with the exception of-the lowermost frustum which has its inner edge fixedly attached to the lower ends of said radial vanes, all of the frusta having inner marginal radial slots adapted to receive said radial vanes to rovide vertical channels'for the full milk in t e neutral zone of the bowl.
